Besides Rajesh Jonnalagadda’s professional suggestion, I would like to supply more information about RSS. A Reporting Services script is a
Visual Basic .NET code file, which defines the Reporting Services SOAP API. A script file is stored as a Unicode or UTF-8 text file with the extension .rss. The script file acts as a Visual Basic module and can contain user defined procedures and module-level
variables. For the script file to run successfully, it must contain the Main procedure.

For example, we can write scripts that set system properties on the report server. The following Visual Basic .NET script shows one way to set properties.
